Hey Bear, thanks alot.
I've gone ahead & bought KYB Xcel G shocks, hopefully they go in with my current springs which i think are just lows not superlows.
I did jack it up a little bit & measured the spring which was 25cm from the top to where it sits at the base, give or take a couple centimeters.
Also measured bottom of the outer sill to the floor was 12cm.
Few of the guys on XF FANATICS have gone with KYB on low shocks, finger's crossed I'm not on super lows, most of the modifications on my car are about 30yrs old now hence there being air shocks which apparently are a thing of the past haha .
It's gonna suck if they shocks don't fit 🥴
